More ferric sulfate must be added if the total weight loss of all specimens exceeds 2 g.

ASTM A763 – 15

It is adtm to ensure that the concentration of acid does not become more concentrated and that an adequate number of boiling chips which are resistant ast, attack by the test solution are present. Welded samples should be bent in such a manner that weld and the heat-affected zone are strained. The copper should be washed and degreased before use. Combinations of zstm and test methods for which successful experience is available are shown in Table 1. This possibility must be considered in selecting the test method.

Gas evolved at the electrodes with entrained oxalic acid is poisonous and irritating. Evaluation by Weight Loss Active view current version of standard. Your Alert Profile lists the documents that will be monitored. Different method of preparing steel test specimens are presented.


An air or hydraulic press may also be used for bending the specimens. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Grain dropping is usually an indication of intergranular attack, but the number of dropped grains per unit area that can be tolerated is subject to agreement between the supplier and the purchaser. To avoid scale entrapment, stamp specimens for identi?
